cat hosts is:
lchata at ubuntu:/etc$ cat hosts localhost ubuntu    ubuntu.gateway.2wire.net    ubuntu

I'm not sure:
lchata at ubuntu:/etc$ cat hostname
lchata at ubuntu:/etc$ hostname
Wht does the command and cat hostname differ?

I really don't know. If I changed the default it was
probably someone's suggestion when struggling to set
up sambe. AFAIK, the above is the default and I listed
what it is know after the changes. I indicated earlier
that hostname & domainname resolve to my computer IP
and name and my gateway/router IP respectively with no
errors on either.  Assuming it's now good although not
a legitimate domain.

Not sure what you mean by resolve. As Indicated above,
hostname and domain name give no errors and point to
computr IP and router/gateway IP. Nslookup point to
the gateway and computer as above but the computer
also point to gateway as follows:
lchata at ubuntu:/etc$ sudo nslookup gateway.2wire.net

Name:   gateway.2wire.net

lchata at ubuntu:/etc$ sudo nslookup

Name:   ubuntu.gateway.2wire.net

lchata at ubuntu:/etc$ 
Which looks ok to me but WDIK.

It's a web mail avscanner or like it from what I'v
read so far.

I could but it's not fully installed or configured so
I don't think it's affecting anything. In it's broken
condition I may not be able to uninstall(not true,
apt* -f install will do it plus all the depends). If
it ain't hurting anything let's leave it. I know what
is keeping it from fully installing. There is no
/etc/mailname which the program depends on.  I asked
about this(if I should create it and add the FQDN or
if some program does it) but seen so answer yet. When
I find out how to get mailname, the amasisd-new will
install, I'm sure.
Thanks for the help; it's appreciated much.
